About the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-30
The AirTAC SAIJ160X135-30 is a double-acting ISO 15552 profile cylinder equipped with a rear stroke adjuster, delivering 10053N of push force at 0.5 MPa. Its 135mm nominal stroke can be dialed back by up to 30mm, creating a precise 105-135mm usable travel window for exact end-position tuning during commissioning. This adjuster acts purely as a mechanical stop to set the retract endpoint and does not hold the load without live air.
Built with a standard carbon steel rod and PT tapered ports, this extruded aluminum barrel omits tie-rods and carries a variable air cushion at both ends. It supports a speed range of 30-500mm/s and uses a reduced mounting subset of Basic, FA, LB, TC, FTC, TCM1, and TCM2, omitting FB, CA, CB, and CR.

Where the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-30 Is Used
Heavy Press Fit Tuning
Dial in the exact 105-135mm insertion depth for heavy press-fit assemblies, ensuring precise end positions without physically swapping out tooling.
Product Size Changeover
Adapt quickly to varying product sizes on a manufacturing line by adjusting the rear stopper to modify the effective stroke on the fly.
Variable End-Stop Positioning
Establish a custom retract endpoint for heavy material handling equipment, using the mechanical stop to fine-tune the machine cycle during initial setup.
Is the Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-30 the Right Cylinder?
Choose this 160mm bore when an application requires heavy thrust around 10053N at 0.5MPa, stepping up from a 125mm bore that provides 6136N. The adjustable stroke is ideal for product-size changeovers on a line, allowing you to fine-tune the retract endpoint without swapping the cylinder or adding external stops. If you need true load-holding without live air pressure, a plain SAIJ is insufficient as its adjuster is only a stop; you should look to the SAIL or BSAI series instead.
For an exact ISO 15552 replacement match, verify the 160mm bore, 135mm stroke, 30mm adjustment range, PT port thread, and the required mounting hardware. Since this unit lacks the -S magnet option, it cannot host CMSE or DMSE sensors for position detection. Although the 40mm rod and M36x2 thread handle high side loads well, an external guide is recommended for any long unsupported travel.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT/NPT/G)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Adjust end cushion screws for smooth stops.
- check Use correct mounting accessory (FA/FB/CA/CB/LB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac SAIJ160 Adjustable Cylinder SAIJ160X135-30 FAQ
At 0.5 MPa operating pressure, this 160mm bore cylinder provides 10053N of push force and 9425N of pull force. It can reach a maximum push force of 18095N at 0.9 MPa.
The rear adjuster screw allows you to shorten the 135mm nominal stroke by up to 30mm, providing a usable travel window of 105-135mm. This mechanical stop fine-tunes the end position but does not lock or hold the load without continuous air pressure.
